This material -falls into an vapron 56 terminating at 58past the discharge point 61 o f the crusher.

For oscillating screen 18,- I mount -a ,itf

tingen bracket 26 forsupporting a shaft 60 -onwhich the end clips 62 ofpitmen 64 are journaled; .Similar clips engage pintles 66 carried by thescreen intermediate its ends.

It will bexapparent that a rather rapid oscillatory motion will beimparted vto screen 18 when the Crusher speed.

Suitable brackets 74, one fastened to crusher 12-` and.another to one of the u'prights 48, carrywheels 76 engaging tracks 70 tosupport the screen and a ron.

apparent that b setting'the tracks at -oppo-;

site ends at'di' erent angles, :a`slight movement of rotation could alsobe employed if sufficient for certain classes of work, and

operates .as follows :'-T11e operator stands -on-screen 18, and throwsto one side pieces of material too large to pass between bars 46. -Bymeans ofgale 50 he controls the owfrom the hopper to the screen, todeliver material to the crusher as fast as the `crusher can handle it.The material fallingthrough 'the -screen travels down apron 56, and isjoinedkbefore leaving` the apron by falling from thev discharge 61 of Inthis .way the lower end of apron 58 delivers' the finished aggregatechiefly on the nature'of the'material handled, and the exa'ctness withwhichv the maximum size of particle inthe finished aggregate mustbehmited, it is `desirable the Crusher to deliver particles of maximumsize considerably in excess of the diameter of holes '54, so that afractionfof the dis-- charge from the' crusher lwill always be returnedto the crusher 4for -,a second passbefore it is reduced to a size thatwill pass screen 18.

This vaccomplishes .two results.

First, screen 18 is A the element determining the -size of particledelivered, rather than the crusher, and the maximum size lcan bedetermined in this way with considerably greater accuracy. Second, thecrusher can be set with a slightly Wider discharge aperture, and .villhandle more material with such an adjustment.

The structure I have illustrated for returning the crusher. discharge tothe scrcenf comprises "a laterally vdirected chiite 86 eceiving thedischarge from the crusher and -delivcringit to a suitable conveyor 88,

.which conveyor .elevates the material and drops' it on chute 90, fromwhich it falls" back on screen 18.

Conveyor'88J may befrendered operative or inoperative, simply "byremoving' or re placing chute 86.' Whether it is employed or not, thedischarge fromv apron 58 will be the finished aggregate ready for use. aI prefer to employ aVl readily vportable storage receptacle 92, seeFigure 1, forre- .ceiving this aggregate, whenever it is necessary tostore a certain amount of the aggregate for periodical delivery to wheelbarrows, wagons, motor trucks," etc. This bin may be of the ty edescribed in my copendin'g application, filed July 8th, 1922.
